CUT-OFF FOR GASOLENE-FAEED ON' MOTOR-VEHICLES.

To all 'LU/1,0m t may concern.'

Be it known that I, BERNARD W. RICHARDS, a citizen of the United States, residingat Chicago, in the county of Cook and 'State of Illinois, have invented certain new and `useful Improvements in Cut-Offs` for Gasolene-. Feed on Motor-Vehicles, of which the fol.`

lowing is a specification. i f

The object of this invention is to provide an easily operateddevice of simple construc- -v tion for shutting Yoff the fuel feed to an internal combustion engine and thereby,` in effect, lock the engine so that it cannot be used.

My invention is intended primarily for use on automobiles, trucks and the like to prevent them from being stolen, and it can be easily installed in the feed line between the supplyand the engine on cars now'in v use as well as on'new cars being built.

In the accompanying drawings illustrating@ selected embodiment of the invention,

igure 1 is a sectional elevation of ank automobile having myk .invention installed in the feed pipebetween the rear `tank and the engine;

Fig. 2 is an enlarged elevation of the device, partly in section;

Fig. 3 is a vertical sectional'view `on the line 3-3 of Fig. 2;

Fig. 4 is a horizontal sectional Aview on the line 4 4 of Fig. 3.

In thedrawings 5 is the feed pipe running from a rear tank 6 or other source of supply to the carbureter 7 of the engine 8. A

gear 9 is rigidly mounted on the stem of valve 10 of any suitableV kind which is interposed in the pipe 5, and this gear meshes with a rack 11 on the push bar 12 which slides in a suit-able channel guide 13 and is provided with a head 111. The bolt 15 of a lock 16 is arranged touengage a lug 17 on the bar 12. The lock maybe any one of many different kinds suitablek for the purpose in which thebolt is normally under spring pressure to project it forwardly and is retracted by means of a key 18. A spring 19 operates againstfthe end of the push bar to hold it normally in outward position with the valve open. When the push bar is thrust inward to close the valve and shut off the fuel feed the lug 17 is carried beyond bolt 15, ,which is thereupon projected forward and engages with the lug to hold the push bar and valve in locked position until i Specification of`Lette1's Patent. ,i

Patented'oct. 4, 1921.

Application filed March 18,1920. lSerial No. 366,773.

1the `bolt is againy released Vby means of the In the drawingsI have shown the several parts of my invention inclosed within a casing 2O,A which maybe conveniently secured iin the Hoor-board at the drivers seat and with the fuel feed pipe 5 passing therethrough. "The device may be made complete for installation in vehicles now in use .by simply cutting the fuel feed pipe and connecting its ends to the ends 5 of the p ipe section including the valve which is yrigidly secured by nuts 21 in the casing. The guide 13 is mounted on one side of the casing and the push bar may be bored at its lower end to receive a guide rod 22 which is rigidly mounted on the casing and holds the spring 19 in place. The lock is secured within the casing and the key barrel 23 and the push bar head 14.- above the casing a sufficient distance to eX- tend through the floorboard when the casing isY fastened to the under side of the Hoorboard. Thus the invention can be installed in an inconspicuous manner in the machine vand in any position convenient for operation by the driver.

I believe it will be found more convenient to locate the device in the floorboard adjacent to the drivers seat, where it can be operated by pressure of the foot, but it is perfectly apparent that it may be ar ranged in other positions and that it may be located at any place about the vehicle where it can be operated by foot pressure or manually,-as may be desired. The push bar head and the key barrel may be made smaller in size and located where they will not be especially noticeable, or the entire device may be arranged under the body, adjacent to the supply tank or under the hood, in any place in the fuel feed pipe where it will not be easily .found byanyone unacquainted with its location. I will use a special lock for each device so that the device may only be unlocked by the particular keyr furnished with it.

It will be readily understood that the spring 19 normally holds the push bar in outward position and thel valve open.V When it is desired to lock the engine andthe vehicle, the push bar is forced inward against preferably proj ect the spring and the rack bar shuts the valve,

ficient V*fuel between this Vdevice and the engine to start the engine but not enough to v operated the bolt l5 is Withdrawn from locking engagement with the push bar and the spring 19 forces the push bar to its outward ,position and opens the'valve.

My invention is simple in construction, it can be manuiactured' and installed at a very reasonable cost, is easily operated and it,

affords an effective lock for the engine and the vehicle to prevent the vehicle from being stolen. I am aware that changes in the form and construction of parts and details of lconstruction may be made without departing. from the invention or sacrificing the advantages thereof, andl reserve the right to make all such changes and modications as fairly possible Within the scope of the following claim. I

I claim: f

TheY combination of a casing adapted to be secured to an automobile, a fuel feed pipe for the automobile engine passingV through said casing, a push bar Within said casing projecting. through the casing Wall and having' a bore in one end, a guide roch on the vcasing extending into said bore7 a spring-on said rod between the casing Wall* and said push bar, a valve in said pipe operatively engaged by said push bar, a lug; on said push bar adapted to engage the Wall of the casing'4 to limit outward movement of said push bar, andlmeans to engage the lug to lock the lpush barin inward position.
